Adjustable clip-on optical element device

Abstract

A clip-on optical element device to be clipped on in front of lenses of a pair of eyeglasses or like and conforming to the pair of eyeglasses. The clip-on optical element device comprises a pair of opposite optical elements, a pair of opposite adjustable, flexible, bendable, and shapeable open rims for receiving the pair of optical elements, and a flexible bridge member detachably connecting the pair of flexible open rims together in a spaced apart relationship. The clip-on optical element device further comprises two pairs of upper and lower clips respectively attached to each of the pair of open rims for securing the clip-on device to the pair of eyeglasses. Each optical element has an annular slot in its peripheral surface and a perimeter which substantially conforms with each of the lenses of the pair of eyeglasses. Each open rim has a protruding ridge in its inner periphery surface for receiving and engaging with the annular slot of the optical element. The optical element is retained thereto by a nylon cord which engages with the annular slot and attached between the ends of the open rim.

       2. The clip-on device in accordance with claim 1 wherein said two lower and upper eyeglass securing fasteners further comprise a plastic covering for preventing scratching of said pair of eyeglasses. 
     
     
       3. The clip-on device in accordance with claim 1 further comprising a stop flange attached to said resilient bridge member and adjacent to ends of said first and second half sections for allowing said first and second half sections to fold in one direction. 
     
     
       4. A clip-on device to be clipped on in front of lenses of a pair of eyeglasses, the clip-on device comprising: a. a pair of optical elements each having a channel in its peripheral surface and a perimeter that respectively conforms substantially with each of said lenses of said pair of eyeglasses;   b. a pair of adjustable, flexible, bendable, and shapeable open rims each having a proximal portion with a proximal end, a distal portion with a distal end, an open portion, and a protruding ridge in its inner periphery surface for respectively receiving and engaging with said channel of a respective one of said pair of optical elements and retained thereto by two cords, a respective one of which is attached between the proximal and distal ends and also engaging with said channel of the respective one of said pair of optical elements, each proximal portion having at least one threaded aperture;   c. a resilient bridge member having at least one aperture on opposite end portions and at least one anchor pin at the opposite end portions and extending downwardly therefrom;   d. said proximal portion of each of said pair of flexible open rims aligned with and adjustably connected to a respective one of said opposite end portions of said resilient bridge member, and secured thereto by a respective screw means inserted into said at least one aperture on the respective one of said opposite end portions of said bridge member and threadedly engaged with a respective one of at least one threaded aperture on the respective one of said pair of flexible open rims; and   e. two pairs of upper and lower clips with a respective pair attached to the respective one of said pair of open rims for securing said clip-on device to said pair of eyeglasses.   
     
     
       5. The clip-on device in accordance with claim 4 wherein said bridge member further comprises a first half section and a second half section hingeably connected to the first half section by a pivotably hinged joint for folding said bridge member in half. 
     
     
       6. The clip-on device in accordance with claim 5 further comprising a stop flange attached to said bridge member for folding said first and second half sections in one direction. 
     
     
       7. The clip-on device in accordance with claim 5 wherein said second half section of said bridge member telescopically connected and secured to the first half section by a threaded screw. 
     
     
       8. The clip-on device in accordance with claim 4 further comprising a cover for covering each of said two pairs of upper and lower clips to prevent said two pairs of upper and lower clips from damaging said lenses of said pair of eyeglasses. 
     
     
       9. The clip-on device in accordance with claim 4 wherein said open portion of each of said pair of flexible open rims are facing inwardly toward each other. 
     
     
       10. The clip-on device in accordance with claim 4 wherein said open portion of each of said pair of flexible open rims are facing outwardly away from each other.
